SPECIFICATION forming part of Letters Patent No. 528,260, dated October30, 18x94. Application filed April 9, 1894. Serial No. 506,795. (Nomoclel.)

To @ZZ whom t may concern.-

Beit known that I, ADOLPHE RODER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inAir-Tight Packages; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofret'- erence marked thereon, which form part of this specification.

My invention relates to improvements in airtight packings for pickles,pickled meats, fruits and other preserves, and the object of the same isto construct an airtight covering for the receptacles of such, whichm'ay easily be removed and partly replaced after opening, so as to keepthe pickles and preserves in good condition even after having removedpart of the same. I attain these objects in the manner shown on theaccompanying drawings, in which- Figure 1 representsa keg provided withthe complete covering, one side ofthe ligure showing one half of avertical section, the other side onehalf of a front view. Fig. 2represents a jar provided with the complete covering, one side of thegure showing one halt' of a vertical section, the other side one half ofa front view. Fig. 3 represents on the left side, one half of ahorizontal section on line A-A, (Fig. 2.) with the presser or weight cremoved and showing the slits b in the wax orparchment paper sheet b, onthe right side one half of the top view of the closed jar. Fig. 4represents a top view of the presser or weight, indicated by c,in Figs.l and 2, and provided with the holes or perforations c', the number,position, and size of which is not limited. Fig. 5 represents a sectionon line B-B, (Fig. 3.) ofthe hoop, indicated byf in Figs. l, 2 and 3.Fig. 6 yrepresents a section on line B-B of the muslin, canvas orbladder cover, indicated by e in Figs. 1, 2 and 3. Fig. 7 represents asection on line B-B of the outer wax or parchment paper, indicated by din Figs. l, 2 and 3. Fig. 8 represents a section on line B-B of thepresser or weight, indicated by c in Figs. l and 2, and shown in topview in Fig. 4. Fig. 9 represents a section on line B-'B ofthe inner waxor parchment paper, indicated by bin Figs. l, 2 and 3.

Similar letters refer to similar parts in the various figures onv thedrawings.

a. is the keg, with the hoops 'a'.

a" is the jar; b, a pieceof parchment or wax paper, provided with theslits b; c, a presser or weight of wood, porcelain or any other suitablematerial with the perforations c. a

d is another heavierparchment paper; e, a piece of u'nbleached muslin,canvas or bladder;f, a hoop of wood or metal o r an elastic ring.

The principle is the following: When the receptacle a, a is lled withthe pickled meat or preserves, the parchment or wax paper b, wellmoistened with th'e preserving liquor, is laid on top in such a manner,that the edges shall not project over the top of the presser c. Theparchment or Wax paperb has one or more slits b. After the parchment orwax paper b is laid on, the weight or presser c is put in place'andpressed down, until flush with the top of the vessel. This pressure willcause the liquor to rise through the slits in the parchment or wax paperb, and to fill the holes in the presser and the spaces around, thusforming a supply of liquor to replace such as will soak into the meat orpreserves. On the top of the presser c is laid another heavier piece dof parchment or wax paper, and on the top of this a piece of muslin,canvas or bladder e, both well moistened and projecting around the rimof the vessel, so as to project under the hoop f when in place. Then thetwo projecting edges of wax or parchment paper and muslin, canvas orbladder covers, while wet, will be drawn down around the upper edge ofthe vessel by the hoop or elastic ringf, which then will be drawn tightor driven down tight. of the covers d and e are cut'J even with thelower edge of the hoopf. After this the upper layer, viz: the muslin,canvas or bladder, is covered and made impervious to moisture, by firstgiving it a coat of thin paste, and

After this the projecting edges when this is dry, one or more coats of-varnish, paint, shellac or solution of rubber. After this the packageis ready for labeling and shipment. The appliance of the coating ofpaste has the purpose of preventing a contact of the varnish or paintthrough the muslin or canvas With the pickle', which would give thepreserves a bad taste.

The advantages Yof this packing are, that the covering is positivelyairtight on'account of the coating, that the preserves can in no way getany taste from the varnish or paint used, on account of the firstcoating with paste; that the opening of the package is very muchfacilitated in comparison to other packings in the market, as it is onlynecessary to out around the edge of the covers above the hoop, about online g--g and without removing the hoop, and to lift out the presser c;further that the presser will always act as a weight on the pickles orpreserves, when the package is once opened, and will prevent them fromdrying out.

The packages may be used over and over again, as only the paper andmuslin or canvas covers are destroyed, the other parts re mainingintact. These covers are appliable to any kind of receptacles, either ofwood,

glass, china, metal, porcelain lined or not, and can be applied andremoved with ease.

What I claim as new in myinvention, and desire to have secured byLetters Patent, is the following:

The combination of a preserving jar or keg or a similar receptacle witha wax or parchment paper layer b with slits b' a presser c with theholes or perforations c', a Wax or parchment paper layer d, amuslin,canvas or bladder layer e, the latter two being stretched overthe edge of the above mentioned receptacle and heldin place by ametallic or Wooden hoop or elastic ringf, drawn or driven tight over theedges of cl and e and around the collar of the above mentionedreceptacle, all these forming a cover for the above mentioned vreceptacle, coated and made airtight with a coat of paste and one ormore coats of paint, varnish or other suitable materia1,allsubstantially as set forth and described.

In testimonywhereof Iaflix my signature in presence of two witnesses.
